Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to an anti-pinch safety zipper. Background Art

[0002] A zipper is a fastener that uses a row of teeth to connect or separate items. It is now widely used in clothing, bags, tents, etc. It is a fastener consisting of two strips with a row of metal or plastic teeth on each side. It is used to connect the edges of an opening (such as clothing or bag openings). A sliding piece can pull the two rows of teeth into an interlocking position to close the opening. It is a chain that is connected to an object (as an object to be lifted or lowered) to tighten, stabilize or guide the object.

[0003] Existing zippers are usually sewn with a cloth bag and the lining of clothes. Since the chain and the lining of the clothes are distributed relatively evenly and the zipper buckle is close to the lining of the clothes, when the lining of the clothes has many wrinkles, it may be caught in the zipper head, which may cause the zipper head to be stuck, thus affecting the user experience. Therefore, we need to propose an anti-pinch safety zipper. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: an anti-pinch safety zipper, comprising:

[0024] Two groups of pull cloths 1, and two groups of pull cloths 1 are provided with multiple groups of chain teeth 2 at opposite ends;

[0025] The anti-pinch slider 3 includes an inner clamping plate 31, a connecting guide plate 32 and an outer clamping plate 33. The inner clamping plate 31 and the outer clamping plate 33 are fixedly connected on both sides of the connecting guide plate. The inner clamping plate 31 and the outer clamping plate 33 are fixedly connected to the limiting plate 34 on both sides adjacent to the connecting guide plate 32. The limiting plate 34 is fixedly connected to an anti-pinch partition plate 35 on the side opposite to the connecting guide plate 32. Both ends of the opposite sides of the two corresponding groups of anti-pinch partition plates 35 are provided with circular chamfers. One side of the anti-pinch partition plate 35 is arranged in the same plane as one side of the limiting plate 34. The lower end of the inner clamping plate 31 and the outer clamping plate 33 is fixedly connected to a guide plate 37 on the side opposite to the connecting guide plate 32.

[0026] The lower ends of the two corresponding groups of limit plates 34 and the anti-pinch partitions 35 on the opposite side are fixedly connected with a clamping plate 36. The length of the clamping plate 36 is less than the length of the anti-pinch partition 35, and the length of the connecting guide plate 32 is less than the length of the inner clamping plate 31. The clamping plate 36 facilitates the mutual engagement of the chain teeth 2, thereby facilitating the closing of the zipper. At the same time, the length of the anti-pinch partition 35 is extended to prevent the slider from getting stuck in the lining of the clothes.

[0027] The upper ends of the two groups of pull cloths 1 are provided with upper stop blocks 6 located above the chain teeth 2, and the lower end of one group of pull cloths 1 is provided with a lower stop block 5. The lower end of the other group of pull cloths 1 is fixedly connected with a movable pin 8, and one end of the upper surface of the lower stop block 5 is provided with a socket 7 for the movable pin 8 to be plugged in. The position of the anti-pinch slider 3 is restricted by the upper stop block 6 and the lower stop block 5 to prevent it from detaching from the pull cloth 1.

[0028] A connecting piece 9 is fixedly connected to the side of the outer clamping plate 33 opposite to the connecting guide plate 32, and the connecting piece 9 is clamped with a quick-release pull piece 4. The connecting piece 9 facilitates the rapid disassembly and assembly of the quick-release pull piece 4, thereby facilitating the maintenance of the anti-pinch slider 3, avoiding the pull ring 44 from affecting the maintenance, and reducing maintenance obstacles.

[0029] The connecting piece 9 includes a connecting block 91, both ends of which are provided with inner holes 92, the bottom of the inner hole 92 is fixedly connected with two groups of springs 93, and the two groups of springs 93 are fixedly connected with a clamping block 94 near the open end of the inner hole 92. The springs 93 resist the clamping block 94, which makes it easier for the clamping block 94 to clamp the quick-release pull piece 4, thereby improving the installation efficiency of the quick-release pull piece.

[0030] The quick-release pull piece 4 includes a handle 41, both ends of which are provided with mounting grooves 48, a pressure rod 49 is inserted in the mounting groove 48, both ends of the inner cavity of the handle 41 are provided with card slots 46 for inserting a card block 94, and the top of the card slot 46 is provided with a storage groove 47, the lower end of the pressure rod 49 is fixedly connected to a pressure block 410 slidably connected in the storage groove 47, and the pressure rod 49 is pressed to make the pressure block 410 contact the card block 94, so that the card block 94 is separated from the card slot 46, so as to facilitate the quick removal of the handle 41.

[0031] The quick-release pull piece 4 also includes a pull ring 44, a hidden hole 45 is provided at the upper end of the pull ring 44, a connecting pin 43 is inserted into the hidden hole 45, and a through hole 42 for the connecting pin 43 to pass through is provided on one side of the pull handle 41. The pull ring 44 can be quickly and conveniently installed through the connecting pin 43, thereby facilitating the pulling of the anti-pinch slider 3, thereby improving the convenience of use.

[0032] When in use, the pull handle 41 is driven to move through the connecting pin 43 on the pull ring 44, and the pull handle 41 drives the connecting block 91 to move through the card block 94 positioned by the card slot 46, so that the anti-pinch slider 3 moves along the pull cloth 1, and the chain teeth 2 on the pull cloth 1 are engaged with each other through the clamping plate 36 and the guide plate 37, so that the zipper is closed. At the same time, during the movement of the anti-pinch slider 3, the anti-pinch partition plate 35 on the limit plate 34 separates the pull cloth 1 from the corners of the lining, thereby preventing the clothes from being stuck between the inner clamp plate 31 and the outer clamp plate 33, thereby improving the safety of the zipper and avoiding the lining from being clamped when pulling the anti-pinch slider 3, thereby ensuring the smooth effect of the zipper and improving the user experience.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
